Application filed Decemlier 31,1904. Serial No. 239,114.

of which'the following is a specification, ref-3 erence being had therein to the accompany ing drawings.

in hydrocarbon-burners, and more particularly to that class of hydrocarbon burnersin' which a coil 'of ,the hydrocarbon-pipe is ar-; ranged in'thepathf of .the burner-jet, soas to; 15. constitute a vaporizer; and the'object ofthe:

- invention is the provision ,of aburner of this nected with a tank in w connection between the containing the air and t a' can be mixediwithoil to cause a blast from the burner to facilitate heating the vap' 2 5 orizing-cil when the burneris 'started, and

1portion of the tank meansfor cutting off the air 'supply to the burner after it is started.

'A further object is the provision of a hoodsurrounding the vaporizing-coil and soco'n- J 3o structed as'to greatly faci itate the heating of said coil In the drawin s accompanying thisspecification, wherein ike numerals of reference re- I fer to similar parts in the several views, and- 3 5 wherein a referable embodiment 'of my in vention is s own, Figure 1. is a side elevation, partly in section, of my improved burner connected to the gasolene-storage tank. Fig. 2

. is a sectional view of the vaporizer-coil and 40 the hood secured thereto, and Fig. 3 is a similar view showing a modified form of hood.

Referring now more particularl to the drawings, A designates a tank a apted to contain gasolene or other hydrocarbon fluid,

and B designates an air-pump connected by a ipe .b with theupper portionthereof and a apted to compress air in the upper portion of said tank above the gasolene therein.

'O designates the mixing-chamber of the burner, which is the form of a horizontally-disposedpipe, one end of which is connectedby a pipe 0 to the lower portion of the asolene-storage tank A. A needle-valve 0 1s interposed between the mixing-chamber C 5; and the tank A to regulate. the amount of liquid fuel furnished to the burner; The

Theburner consists of a sin le tube folded upon itself to form a helical Ynect'ed to the forward... end of the jmixingchamber [O so as; to form a continuation thereof, andthe other terminal of which, (1,

.. is extended parallel with the-axisfof the; coil.

Secured to theend of the terminal-d is a small tube (1?, which has its free end bent back 11 on itself to lie in axial alinement with the coiljthe free end of said-tube constituting aburIier-tip. v

thereby giving a very powerful flame, which is very necessary in brazing operations and v The hood E is provided with a longitudinal slot e therein, adapted to reoeive'the terminal (1 of the coil D when" the hoodis slipped thereon, said slot being provided with a lateral extension 23' at the upper end thereof, so that the hoodv may .be locked to. the coil after it'has been slipped thereon by giving it a slight turn. The inner portion of the hood duced by either tapering the projecting por tion of the hood, as shown in Fig. 3, or by providing the outer end of said hood with an abrupt annular flange e, as shown in Fig. 4. A plurality of elongated slots 6 are formed in the portion of the hood fitting over the coil E, the upper ends -of which extend slightly above the outermost wrap of the coil E and terminate in the outwardly-extending flange e Having burner, Iwill now proceed to set forth the operation of the same. The needle-valve c in the gasolene-pipe is first opened, and-the asolene ,which will .then issue from the urn'er-tip isignited. The valve 0 is then opened to allow compressed air to pass from described the construction of my 7 v E is ofa size to snugly fit over the coil D, and

thetop of the tank A to the mixing-chamber ,C, where it mingles with the gasolene and H causes the same to issue from the burner-tip the coil D and which will consequently in ashort time heat said coil to cause the vaporization of the liquid contained therein. As the flame completely fills the interior of the coil 1) and as the outlet or the hood E is of a smaller diameter than the interior of said coil, a portion of the flamewill be deflected back and will be caused to pass through the slots 6 in the hood E and impinge upon the exposed portions of theback of the coil D, thereby facilitating the heating of the coil in starting-the burner and serving to keep the coil hot at all times after the burner has been started. As soon as the burner is started the air-valve c is turned off and vaporized hydrocarbon only is burned at the burner-tip.

I do not desire to limit myself to the precise form and construction shown in the drawings, as it is obvious that many minor changes might be made thereto without departing from the spirit of the invention. I

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is

. 1. In an apparatus of the character described, a tank adapted to contain a supply of liquid hydrocarbon, means for supplying compressedair to the upper portion of thetank above the liquid contained therein, a burner, a horizontally-disposed mixing-channher, a vaporizing-coil arranged adjacent the burner connected to one end of the horizontally disposed mixing chamber, separate pipes connecting said mixing-chamber with the upper and lower portions of the tank andpennitting the entrance thereto of independent jets of oil and air, and valvesfor controlling the flow of air and fuel to the mixing-cham ber, Wherebyeither a'rnixture-of o l and air or Oll alone may be supplied to the burner.

.2 In an apparatus of the character described, a tank adapted to contain a supply of liquid hydrocarbon, means for supplying compressed air to the upper portion of the tank above the liquid contained therein, a

'opposite end, of the horizontally-disposed mixing-chamberwith the lower end of said tank, and a separate pipe connecting the mixing-chamber and the upper portion of the tank, and valves for controllingthe flow of oil and air to the mixing-chamber, whereby either a mixture of oil and air or oil alone may be supplied to the burner.

3. In an apparatus of the character described, a tank adapted to contain a supply of liquid hydrocarbon, means for supplying compressed air to the upper portion of the tank above the li uid contained therein, a burner, a horizonta y-disposed'mixing-chamher, a vaporizing-coil arranged adjacent the burner, a connection from the mixing-chamher to the vaporizing-coil, said connection extending from one end of and in alinement with the mixing-chamber, a pipe connecting the opposite end of the horizontally-disposed mixing-chamber and the lower portion of the tank, a separate pipe extending from the upper end of the tank to the mixing-chamber intermediate its connection with the first pipe and thevaporizing-co1l, and valves in said pipes controlling the flow of oil and air to the mixing-chamben In testimony whereof I affix my signature in presence of two witnesses FRANK C. LORING. Witnesses:
